When do you plan to open up public beta?

Our development teams tried Mingle in the past, but it was so complicated and hard to figure out that we just went back to using Basecamp (which of course is great for "big picture" stuff for the execs but has its own limitations for agile development).

Tracker is such an awesome product that we can't wait to start using it for all of our projects. When do you plan to release public beta so we can start adding multiple projects?
